Reactions of 1,3-thiazine-2,6-dithiones. Part 5. Novel synthesis of 3,5-dicyano-4-thiopyridones via 2-cyanomethyldihydro-1,3-thiazine-6-thiones

A novel synthesis of a series of 2,6-disubstituted 3,5-dicyano-4-thiopyridones 4 by the decomposition of 2,4-disubstituted 5-cyano-2-cyanomethyldihydro-1,3-thiazine-6-thiones 2 , which are synthesized from 4-substituted 5-cyano-1,3-thiazine-2,6-dithiones and enaminonitriles, is described.     

Super Yang–Mills theory from nonlinear supersymmetry

The relation between a nonlinear supersymmetric (NLSUSY) theory and a SUSY Yang–Mills (SYM) theory is studied for N=3$N=3$ SUSY in two-dimensional space–time. We explicitly show the NL/L SUSY relation for the (pure) SYM theory by means of cancellations among Nambu–Goldstone fermion self-interaction terms.
